Patent number: 11376718Abstract: A packing screw removal tool for removing packing from a pump fluid end comprising: a tool body; a plurality of packing screw engagement dogs distributed about an axis of rotation about the packing screw removal tool; and a torque transfer engagement post coupled to the tool body. The engagement dogs align with and are releasably connected to radial locations on the packing screw. Applied torque is transferred through a torque transfer engagement post, through the tool body to the engagement dogs and into the packing nut. A second torque transfer engagement post is smaller than the first engagement post. The shape of the tool body allows rotation in limited or confined space. A pump may be serviced at the wellsite by utilizing the packing screw removal tool to unthread the packing screw from the fluid end.Type: GrantFiled: April 3, 2020Date of Patent: July 5, 2022Assignee: Halliburton Energy Services. Inc.Inventors: Kristopher A. Benz, Brandon Stackhouse

Patent number: 11077540Abstract: A shaft assembly has a central rod, a braided cable, and a coupling there between. The coupling receives the lower end of the central rod and the upper end of the braided cable. A fastener has an upper end with a cylindrical extension for coupling with the lower end of the braided cable. A handle has an upper region with a cylindrical extension and a lower region with a cylindrical flange with a left tab and a right tab. A slide hammer is configured to be vertically reciprocable along the shaft assembly. The slide hammer has an upper region with an upper cylindrical flange. The slide hammer has a lower region with a lower cylindrical flange with a lower extension.Type: GrantFiled: July 24, 2019Date of Patent: August 3, 2021Inventor: Jeremy Dewitt

Patent number: 9908224Abstract: Gland puller for use in rebuilding hydraulic cylinders. Upon insertion of the first end of the elongated rod into a shaft hole of the hydraulic cylinder gland assembly beyond a first point, the rotating protrusion member is configured to rotate from the first position to the second position, and upon rotating the threaded collar along the threaded portion towards the first end, the elongated rod is configured to be pulled back from the first point to a second point where a surface of the at least one end of the rotating protrusion member is configured to abut an inner surface of the hydraulic cylinder gland assembly while a surface of the threaded collar is configured to abut an outer surface of the hydraulic cylinder gland.Type: GrantFiled: December 31, 2015Date of Patent: March 6, 2018Inventor: John Harmon

Patent number: 9902053Abstract: A knockout removal tool includes an electrical box. The front side is open. The electrical box may be positioned within a wall such that the front side lies on a plane that is planar with an exposed surface of the wall. A handle has a first end, a second end and an outer wall extending therebetween. The first end is flat. The second end is convexly arcuate. A rod is coupled to the first end. The rod has a distal end with respect to the first end. The rod is inserted through the electrical box such that the distal end is directed toward a knockout in the electrical box. A head is coupled to the rod. The head engages the knockout to facilitate removal of the knockout after the electrical box has been installed and trimmed.Type: GrantFiled: December 17, 2014Date of Patent: February 27, 2018Inventor: Felix Vivas

Patent number: 9126315Abstract: A hand tool for removing flexible strips used to retain windows and screens onto doors. Each of the two blades of the strip all is optimized for use in removing one of the two flexible strip designs currently in use. The geometry of each blade is designed for ease of use and to protect the door, window, screen or operator from damage.Type: GrantFiled: February 9, 2010Date of Patent: September 8, 2015Inventor: James Leroy Balliet

Patent number: 7472716Abstract: A valve having a valve packing removal device attached thereto is disclosed. The valve may include a valve plug reciprocally disposed within the valve housing and connected to a sliding stem. The packing may be provided about the valve stem to ensure or minimize leakage of regulated fluid from the valve. A sleeve may have a diameter less than a bore in which the packing is disposed and may be connected to the valve stem such that when the valve stem is sufficiently pulled from the valve, the sleeve engages the packing and pulls the packing from the valve.Type: GrantFiled: February 6, 2007Date of Patent: January 6, 2009Assignee: Fisher Controls International LLCInventor: Douglas P. Gethmann

Patent number: 6918320Abstract: A packing tool or set of tools having a handle and one packing end that is formed to perform various tasks involved with packing fiber into conduits without damaging insulation on wires in the conduits. The tools are made of a non-conductive material that has a smooth surface on the packing end or ends with no sharp edges. In one embodiment the tools are made of injection molded plastic and are lightweight. One tool has a hook for picking up a single wire on one end, and a larger hook on the other end for picking up multiple wires. A further tool has a first end for packing and a second end with a mirror that is angled to facilitate inspection of the packing.Type: GrantFiled: November 20, 2002Date of Patent: July 19, 2005Assignee: Cooper IndustriesInventors: Benjamin E. Merrill, Jr., Billy Dale Wann

Patent number: 6625510Abstract: A computer-based system to create and modify documents used in a tool management program. A word processing module is used to create the document, in conjunction with a graphics module. The graphics module includes representations of all of the tools used in a maintenance program, as well as representations of toolbox panels into which the tools are placed. A user simply drags selected tools into selected panels to. create a tool-filled panel graphic which may be directly imported into the document in the word processing module. The tools also have certain attributes defined by associated data. A data interface arrangement is operable to convey certain selected data from the graphics module to the document in the word processing module, after preselected sorting.Type: GrantFiled: June 13, 2001Date of Patent: September 23, 2003Assignee: The United States of America as represented by the Secretary of the NavyInventors: Harold A. Kimball, Robert R. Carbrey

Publication number: 20030029277Abstract: A tool for inserting and removing gaskets from hose couplings includes a shaft having a nose and heel attached at one end of the shaft. The heel includes a flat, bottom surface that is pressed against the gasket in order to push the gasket into place. The heel may have a sufficiently large surface area to not cause undue markings or damage to the gasket when it is inserted. When the gasket is to be removed, the nose is inserted between an underside of the gasket and the gasket seat. The heel is then moved into contact with the gasket seat and used as a fulcrum by which the nose is lifted away from the gasket seat. This lifting movement causes the gasket to be lifted out of the hose coupling.Type: ApplicationFiled: July 17, 2002Publication date: February 13, 2003Inventor: Mark G. Lummis
